Roc Nation knows how to treat its clients. For Christmas, the management company wrapped up a Porsche 911 Turbo S for Rihanna... and recently hooked up WNBA rookie Skylar Diggins with a new Mercedes for graduating from college.

The 22-year-old basketball player graduated from Notre Dame recently, and Jay-Z's Roc Nation Sports presented her with a new Benz as a graduation gift. Diggins is among Jay-Z's first high-profile clients of Roc Nation Sports, which also includes Yankees' Robinson Cano and Giants wide receiver Victor Cruz.

She was an All-America guard for the Fighting Irish, and was taken third overall in the WNBA draft by the Tulsa Shock.
